q

I don't know what is the exactly difference between AngularJS $q service and simply using .then() after async request. Simple example with .then() : function InboxService($http) { this.getEmails = function getEmails() { return $http.get('/emails'); }; } And when using the service (just part of code): InboxService.getEmails() .then(function (response) { // use response }); What is the difference with $q service with resolve and reject ? What is the difference with $q service with resolve and reject ? I assume you are asking about the usage of var deferred = $q.defer() with subsequent deferred

I am creating a single page app built on AngularJS, Breeze, and RequireJS. In setting up AMD with requirejs to work with Angular and Breeze, I encountered an issue with Breeze's dependency on "q". If the configuration rule for "q" is lowercase, even if there is no explicit export in the "shim", Breeze gives this error: Uncaught Error: Unable to initialize Q. See https://github.com/kriskowal/q "http://localhost:1498/Scripts/shared/breeze.js"breeze.js:1` When require config changes all references from "q" to "Q" (even without the export), the code works. Does anyone know why this is happening?

I looked at lot of example but couldn't achieve it..so need help.. Problem.. the content from loop should be passed to execute one by one. each loop iteration contains a file read and database save operation along with few other object properties that need to be assigned. I have created example here.. http://runnable.com/VI1efZDJvlQ75mlW/api-promise-loop-for-node-js-and-hello-world how to run: Api: http://web-91b5a8f5-67af-4ffd-9a32-54a50b10fce3.runnable.com/api/upload method : POST content-type : multipart/form-data upload more than one file with name. .. the final expected promise is files

Have a question about synchronizing nested promises when using $q in Angular. Will the following code ensure that the entire chain of promises is waited for? Meaning will the nested calls to services that return promises be waited for in the $q.all block? var call1 = service1.get('/someUr').then(function(){ return service2.get('/someUrl2'); //returns promise }); var call2 = service3.get('/someUr').then(function(){ return 'hello'; }); var call3 = service4.get('/someUr').then(function(){ return service3.get('/someUrl3');//returns promise }); $q.all(call1,call2,call3).then(function(){ console.log

Trying to find the best-use example of returning an array of data in Node.js with Q library (or any similar library, I'm not partial) when using Firebase .on("child_added") ; I've tried using Q.all() but it never seems to wait for the promises to fill before returning. This is my current example: function getIndex() { var deferred = q.defer(); deferred.resolve(new FirebaseIndex( Firebase.child('users').child(user.app_user_id).child('posts'), Firebase.child('posts') ) ); return deferred.promise; } function getPost( post ) { var deferred = q.defer(); deferred.resolve(post.val()); return deferred

following is a short example for using a promise with Q. this is test1.js: function testDefer() { var deferred = Q.defer(); fs.readFile("foo.txt", "utf-8", function (error, text) { if (error) { deferred.reject(new Error(error)); } else { deferred.resolve(text); } }); return deferred.promise; } and this is test2.js (function(){ 'use strict'; var test1 = require('./test1'); test1.testDefer().then( function(data){ console.log('all good'); }, function(err) { //upon error i might want to throw an exception, however, it is not thrown / ignored. throw new Error('I want to throw this exception'); } );

I have a controller that expose a function that returns some text after a rest call. It works fine, but I'm having trouble testing it with Jasmine. The code inside the promise handler in the test never executes . The controller: /* global Q */ 'use strict'; angular.module('myModule', ['some.service']) .controller('MyCtrl', ['$scope', 'SomeSvc', function ($scope, SomeSvc) { $scope.getTheData = function (id) { var deferred = Q.defer(); var processedResult = ''; SomeSvc.getData(id) .then(function (result) { //process data processedResult = 'some stuff'; deferred.resolve(processedResult); }) .fail
